' To all whom it may concern:

. way and closing the same.

Be it known that we, WILSON B. RUNNIoN and EDWARD RUNNION, citizens ofthe United States, residing at Spencer, in the county of Roane and Stateof West Virginia, have invented a new and useful Valve-OperatingMechanism, of which the following is a specification.

The present invention relates more particularly to means for controllingthe passage of gas through supply. conduits or pipes. Under certainconditions, it is of the greatest importance to shut off the gas supply.For instance, the wall brackets are apt to be swung so that the flamefrom the burner will come into contact with the wall or adjacentcombustible material, and cause a coni'lagration. A ain it sometimeshappens that the supply of gas through mains is shut oil for some reasonwithout warning. As a consequence, those burners which are in use areextinguished. When the su ply of gas is again turned on, the gas willpass through the burners, and it is apt to cause explosions orasphyxiation.

The principal object of the present invention is to provide novel,simple and practical means for automatically cutting oil the gas supplyin such contingencies, thereby eliminatlng any danger of the abovecharacters.

The preferred embodiment of the invention is i lustrated in theaccompanying drawing, which is a sectional view through the apparatus,showing portions of the same diagrammatically.

A gas supply conduit 1 includes a valve casing 2, across which extends apartition 3 having an opening 4 therein surrounded by a valve seat 5. Aguiding sleeve 6, preferably of insulating material, is fitted in onewall of valve 7, which closes the opening, and is movable into'and outof co'action with the valve seat 5, has a stem 8 rovided with a head 9that is slidable in 516 guideway or sleeve 6.

An electro-magnet 10 has a core 11 snugly fitted in the outer end 'ofthe sleeve or-guide- This magnet is electrically connected, as shown at12 with a suitable source of electrical energy 13. An-

other lead 14 from the said source of eleccate in this circuit. At 17there is illustrated a-swinging wall bracket burner, which is connectedto the supply conduit, and located upon the wall so as to intersect theflame from the burner should the bracket be is movableinto and out ofengagement with spaced contact elements or arms 25 mounted on andinsulated from the hood or cap 20, as shown at 26. The electric circuitabove described includes the contact elements .25. The casing 2 isfurthermore provided on the wall opposite the guide sleeve with a cap27,

or packing box in which is slidably mounted a reciprocatory stem 28having an outer knob 29am] an inner enlarged head 30, this head beingmovable through the opening and into engagement with the valve stem 7.

The operation of the structure is substantially as follows: Assumingthat. there is pressure in the pipe 1, the diaphragm 21 will he raisedso that the outer end of the stem 23' is in engagement with the arms 25.1f

therefore the switch 15 is closed, the circuit will be closed. Thereforethe magnet will be energized, and if the head 9 ofthe valve is incoacting relation with the core H, the valve 7 will be supported in openposition, as shown. Assume now that the gas is burning at the bracket17. If said bracket is swung to the wall, the flame will immediatelyfuse the conductor 18, and. thereby break the circuit. As a consequence,the magnet will be den'ergized, permitting the valve 7 to drop and closethe opening 4, thus cutting off the supply of gas and extinguishirn theflame before dal'nage is done. ()r with the parts,- as shown in thedrawing, assume that the supply of gas is cut oif and that thereareburners in operation, it will be evident that the pressure in theconduit 1 will be reduced,

thereby permitting the diaphragm 21 to fall. .The stem 23 will gravitateand disengage until the stem 28 is forced upwardly and the valvereturned to open position with the head 9 in coacting relation to theelectromagne't. If in an emergency, it is desired to manually cut offthe supply of gas, it is only necessary to open the switch 15. It willthus be evident that simple mechanism is employed, which materiallyreduces the dangers above described due to the use of gas.

From the foregoing, it is thought that the construction, operation, andmany advantages of the herein described invention will be a parent tothose skilled in the art without urther description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction, may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention. I
